public void setCentroidWorldEnvelopePosition(double xCoord,
                                             double yCoord,
                                             AbstractGRPoint.PointType type)

Computes the zoom of the envelope for the georeferencing scene or the footprint scene.

transformAspectRatioGeorefPartial

public void transformAspectRatioGeorefPartial(Envelope envelope)

Determines the ratio the boundingbox has to orient on. If there is a mismatch between the width and height this should influence the display of the image returned by the WMS to prevent any deformation.

pos - orientation on width because width is larger

neg - orientation on hight because hight is larger

other - orientation on width/hight because they are even

The partial orientation orients on the minimal span dimension.

Parameters:

envelope - to be transformed, mustn't be null.

transformProportionGeorefFullOrientation

public void transformProportionGeorefFullOrientation(Envelope envelope)

The full orientation orients on the maximal span dimension.

Parameters:

envelope - to be transformed, must be not null.

transformProportionPartialOrientationFoot

public void transformProportionPartialOrientationFoot(Envelope envelope)

Transforms the ratio of the dimensions of the footprintPanel.
It takes the ratio between the dimension -width and -height and the ratio between the envelope -width and -height.
